假设我有这个：

<v-btn v-for="action in actions" :key="action.icon" :disabled="action.disabled" icon
       @click="action.click(item.id)">
  <v-icon>{{ action.icon }}</v-icon>
</v-btn>

动作定义如下：

export default {
  props: {
    rowEditingDisabled: Boolean,
  },
  data() {
    return {
      actions: [
        {icon: 'mdi-pencil', disabled: this.rowEditingDisabled, click: this.edit},
      ],
    };
  },
};

如何才能在组件属性“rowEditingDisabled”更新时更新禁用属性？

这是一个片段，展示了我的意思：

Vue.component('child', {
  template: `
    <div>
      <v-btn :disabled="rowEditingDisabled">This works!</v-btn>
      <v-btn v-for="action in actions" :key="action.icon" :disabled="action.disabled" icon
         @click="action.click(item.id)">
        <v-icon>{{ action.icon }}</v-icon>
      </v-btn>
    </div>`,
  props: {
    rowEditingDisabled: Boolean,
  },
  data() {
    return {
      actions: [
        {icon: 'mdi-pencil', disabled: this.rowEditingDisabled, click: this.edit},
      ],
    };
  },
})
new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data() {
    return {
      isDisabled: true
    };
  },
  created() {
    setInterval(() => {
      this.isDisabled = !this.isDisabled;
    }, 1000);
  },
})

当我只使用 prop 时它可以工作，但是当我将它放入数组中时它就不再工作了。
